General Dynamics Ajax (Scout SV)

Armored Modular Fighting Vehicle (AMFV) [ 2021 ]

The British Army AJAX is a highly-modular Armored Fighting Vehicle to fulfill various roles within the British Army - it is based on the Austrian-Spanish ASCOD design.

The British Army is currently developing the Scout SV family of vehicles with General Dynamics (UK). Origins of the vehicle go back into the late 1990s when the British Army sought a modernized, modular, air-transportable (Lockheed C-130 Hercules- / Airbus A400M-class) solution for their aging stock of tracked armored fighting vehicles then in service. Initially, the British teamed with Germany to develop what would become the "Boxer" modular Armored Fighting Vehicle (AFV) but UK involvement in that program ended in 2003. In May of 2004, the "Future Rapid Effect System" (FRES) program was established and contenders became the German Boxer, the Swiss Piranha V, and the French Nexter VBCI - all multi-axle, wheeled AFVs. A restructuring of the program eventually led to none of these vehicles being selected and the FRES program fell to history.

In 2009, BAe Systems and General Dynamics were named as the survivors of the new "Specialist Vehicle SCOUT SV" program brought about by the Ministry of Defense (MoD). On March 22nd, 2010, General Dynamics was declared the winner of the competition and given funding for the design, development, and construction of seven pilot vehicles for testing and evaluation. The MoD expects to field a fleet of 589 Scout SV systems - the production contract (totaling 3.5 British Pounds) was awarded on September 3rd, 2014.

The Scout SV is intended as a modular battlefield AFV that will undertake several prominent roles for the Army and allow retirement of existing, though aged, and rather single-minded vehicles in service. The new vehicle will displace in the 42-tonne range and offer modularity through various armament and component systems fittings to undertake the battlefield role at hand. All forms will utilize the same powerpack, running gear, and general arrangement in order to help keep operational costs to a minimum and repair costs low due to extensive interchangeability of the many parts involved per vehicle. As expected, the vehicle will sport all-modern digital systems with real-time processing, strong protection qualities, and good performance on road and off road - no doubt incorporating those lessons learned from fighting in Afghanistan and Iraq.

The base service model will become the Scout SV, an Infantry Fighting Vehicle (IFV) variant which utilizes a highly conventional design form for its general makeup. A well-sloped glacis plate is seen at front with the driver set to front-left and the powerpack to his right. The turret sits over the middle-rear of the hull roof and provides full 360-degree traversal as well as inherent elevation. Primary armament is a 40mm autocannon with a secondary 7.62mm coaxial machine gun fitting. Smoke grenade dischargers are featured in two banks of eight dischargers at either frontal side panel of the turret to allow the vehicle a self-screening capability. Amphibious travel is possible with propulsion handled by the motion of the tracks. Entry/exit is through a variety of hatches along the hull roof and turret as well as the rear hull panel. The vehicle's running gear includes seven rubber-tired road wheels to a hull side with the drive sprocket at front and the track idler at rear. Side armor skirts will serve to protect the vulnerable upper track spans. The IFV variant crew will total three with internal space reserved for combat-ready infantry.

Onboard systems are set to include panoramic sighting devices, target acquisition systems, a laser warning system, acoustic detection suite, Electronic CounterMeasures (ECM), and other components to serve heightened situational awareness.

The Scout SV designation will serve the basic IFV role and there are several other forms under consideration including the "Protected Mobility Reconnaissance Support" (PMRS), Engineering Reconnaissance, Repair & Recovery (R&R), Command & Control (CC2), and Repair SV vehicles. The PMRS loses the cannon-armed turret of the Scout SV and incorporates a fully-stabilized Remote Weapon Station (RWS) instead. The Reconnaissance model follows suit but installs a bulldozer-type assembly at the bow. The R&R vehicle features the RWS but a smaller bulldozer assembly at front. The CC2 vehicle sports a RWS and installs additional communications gear for the role. The Recovery SV incorporates a powered crane arm over the hull as well as the RWS.

In 2015, the Scout SV program netted a Mobile Test Rig (MTR) for trials and the first pre-production system (in PMRS form) was showcased back in 2014.

The Scout SVis based on the original General Dynamics ASCOD system (used by the Spanish Army). This development began as a joint venture between Austria and Spanish and produced the Ulan and Pizarro vehicles respectively. The line entered service in 2002.©MilitaryFactory.com

June 2021 - Twenty-five AJAX systems have been delivered to the British Army.

September 2021 - Some 20% of the entire AJAX fleet are ready for delivery or have been delivered to the British Army. Up to 589 are still expected for procurement.

November 2021 - Noise and vibration issues have kept the AJAX from entering operational service.

Traverse bodies of open water under own power with / without preparation.
Onboard systems provide solutions to accomplish a variety of battlefield engineering tasks.
Support allied ground forces through weapons, inherent capabilities, and / or onboard systems.
Can conduct reconnaissance / scout missions to assess threat levels, enemy strength, et al - typically through lightweight design.
Special purpose design developed to accomplish an equally-special battlefield role or roles.

Vehicle utilizes a track-and-wheel arrangement to provide enhanced cross-country travel capability.
A modern tank quality, this vehicle sports its main armament in a single turret, typically traversable with an elevation capability in-built.
Vehicle supports a remote-operated weapons station, reducing crew exposure to outside dangers.
Armament is situated in a traversing component, allowing for all-around engagement of enemy threats regardless of the vehicle's facing.
Main weapon has an integral recoil mechanism, allowing the system to remain trained-on-target after firing.
A modern quality, onboard systems provide accuracy to primary armament allowing for firing on-the-move.
System can enter and traverse open water sources - either rivers, lakes, and streams; Amphibious Assault operation support.
The shallow design of the glacis plate provides the vehicle with inherent ballistics protection as well as contributes to a lower overall profile - making it more difficult to disable.
Protection is enhanced by way of additional armor being installed over that of standard levels; plate steel for older designs and reactive armor for modern types.
Crew is provided (either as standard or optional) protection against Chemical-Biological-Radiological-Nuclear agents for enhanced survivability in contaminated zones.
Vehicle has capability to self-generate a smoke screen, either through launched grenades or built-in engine funtion (raw fuel injection).
Crew has access to night-vision equipment, allowing for low-light or night time operations.
System is given an anti-aircraft defense component to protect itself from low-flying aerial threats at range.
Onboard solution provides ability to neutralize armored or fortified targets at range through missile or penetrating ballistic weapons.
Vehicle features an in-built anti-infantry capability for local defense of the vehicle or general troop suppression.
Vehicle supports an unmanned weapons station controlled remotely from within the safety of the vehicle.
Vehicle's proven running gear and overall makeup lends itself well to fulfill other battlefield roles by way of specialized designs.
